What's the wavy thing between the retainer and keepers?

Oh sharp eyes I see ...

yeah... *hangs head* that's the #5 intake valve retainer itself apparently it got hammered on or something (not sure if the chicken or the egg came first?) , and shall be replaced/fixed
#5 Intake valve has problems , and I'm sure it is a sticky valve.. ( fought me a little bit taking it out.. carefully as I could )
#5 won't be going back in ... I slid in #4 , and #6 intake valves into the #5 intake valve guide... with = success.
Rocker looks good though.

Shall be replacing it , and moving forward !

Alright so #5 intake valve was deemed crap on the valve stem.
The problem area was just below the retainer keeper edge = mushroomed.
Even though it was not bent , and had free operation throughout it's range of lift/spinning.... the awful bugger wouldn't come out without a fight.

I then wen't to my spare P79 head , and borrowed a few GOOD intake and exhaust valves (in case I need more , but not likely).

Bad valve on the left (I had to sand it a little to get it out of the guide... grrrrr) , and good valve right .

With all that being said I'm almost done checking the stuff on the head (yeah I take my time lol) , and will re-assemble here soon hopefully.

#6
exhaust valve needs lapping

The rest look good to go after cleaning and inspection (they have been lapped previously not long ago).

shifting gears and moving in a slightly different direction...

I pulled the camshaft and camshaft towers off to make sure all the alignment dowels were in place after a hunch.
For the moment I'll be using a different head.

This is the spare head , and these pictures are in the process of cleaning.

Making sure the oil passages are clear/clean can get a little weird for me. I taped off the entry holes on the bottom to minimize perpetrators.

005 by 71240z, on Flickr

keeping debris out if possible.

Getting ready to lap the valves at this point then trolled myself.... ( I must find my valve lapper first.... doh !!)

I forgot to say earlier I pulled out all the valve train on this head obviously. The lifters , rockers , springs , and pads are in the other box on my workbench. All of these components are in order

016 by 71240z, on Flickr

cleaned all the valves up with a wire wheel. (carbon was much harder to get off some then others .. this miffs me a bit lol)

017 by 71240z, on Flickr

This all should move on along faster at this point ... for the head at least
